Thanks Loren,

I had already found the checkboxes,
I checked WRC329, when that didn't work I also changed the reduced intersection pull down to WRC329.
No RFT/WLT is unchecked.

I have a 1.5" branch with weldolet which is working to WRC329 when I check the SIF scratch pad, but as I said the 3" repad branch gives me 6.012 ii & io (so WRC329 is partly working), if I change the branch type to unreinforced the SIF's change inline with WRC329

Is I doing something wrong or has a decision been made not to include reinforced tees as part of the WRC329 implementation in CII?
